METAL WHEEL-NAVE.

SPEGIFIGATION forming part of Letters Patent No. 738,010, datedSeptember 1, 1903.

Application filed December 28,1901. Serial No. 87,630. (No model.)

T0 at whom it may concern:

Be it known that I, EDMUND PAUL DIGNAN, machinist, a subject of the Kingof Great Britain, residing at Wilmington, in the State of SouthAustralia, in the Commonwealth of Australia, have invented certain newand useful Improvements in Metal Wheel-Naves for Suspension-Spokes, ofwhich the following is a specification.

This invention relates to the construction of an improved wheel-naveofiron or steel or other suitable metal and is intended more particularlyfor the road-wheels of agricultural implements and other vehicularmachinery.

The object of this invention is to construct a Wheel-nave in such mannerthat spokes arranged tangentially to the hub may be tensioned by nuts attheir hub ends. I accomplish this object by constructing a metalwheel-nave having a series of projections or bosses arranged around theperiphery of the same and cast or formed integral therewith, each bossbeing provided with openings arranged tangential to the periphery of thehub, having flat surfaces at the ends of the said openings and at rightangles to the same adapted to form seats for the spoke-nuts. In this waya wheel may be constructed in which tangent-spokes can be tensionedindependently by nuts at their hub ends.

My invention will be the more clearly explained by reference to theaccompanying drawings, in which- Figure 1 is a side View of a wheel withmy improved nave; Fig. 2, a longitudinal side view of the nave; Fig. 3,a longitudinal section of Fig. 2; Fig. 4, an end View of the nave; Fig.5, a cross-section on the line Ct b of Fig. 2; Fig. 6, a cross-sectionon the line 0 d of Fig. 2.

By reference to the drawings it will be seen that the hub or body of themetal wheel-nave is constructed with a series of solid projections orbosses A, extending around its periphery. The projections or bosses Aare cast or formed integral with the nave and are drilled or molded withspoke holes or openings for the spokes arranged tangential to theperiphery of the nave. At the ends of the holes or openings B the bossesor projections A are provided with seats for the spokenuts at rightangles to such holes or openings B. The spokes O are passed through thespoke-holes in the rim and then through the spoke holes or openings B inthe projections or bosses A and are thus arranged tangentially to thehub and radiate from the nave to the rim of the wheel. Nuts are thenscrewed upon the spokes 0 against the seats 011 the bosses orprojections A at the ends of the openings B. In this way each spoke canbe tensioned independently by its nut at the hub end.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- A hollow wheel-nave of the same diameter throughoutprovided throughout its periphery with a series of independent integralbosses extending at an inclinationwith respect to one another, each ofsaid bosses pro-- vided with spoke-receiving openings arrangedtangentially to the periphery of the nave. and further provided withfiat surfaces extending at right angles to the ends of thespoke-receiving openings to form seats for the spokenuts, substantiallyas herein shown and described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

EDMUN PAUL DIGNAN.
